'32 trans mount to torque tube cup bolts

[russcc]

Looking to find what I believe are a 1 year only special bolt that has a head on it that locks into place in the groove on the '32 trans mount so it won't turn when you tighten up the nut on the U-Joint cup. I can post a photo of where in goes in the later mounts that are like the '32, but the '32 bolt is longer, probably because it also goes through the K member.
